TO ALL WHOMIT MAY OOINOERN:

Bc it known that I, ROBERT THOMAS, oi' Parkersburg, 1n the county of Wood, and State ot' West Virginia, have invented a new and useful Improvement in Windo\\-Sasl1es; and I do hereby' declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawingsi`orlning part of this speciiication, in which- Figure 1 is a front View of a window, having the sashes fitted in it and arranged according to my invention.

Figure 2, a vertical section of the same, taken in the line :v at, fig. l, and looking in the direction indicated by arrow l. i

Figure 3, a vertical, section of' the same, also taken in the saine line, a: rv, iig. l, but looking in the opposite direction, indicated by arrow 2.

Figure 4, a detached side or edge view of the two sashes.

Figure is also a detached side or edge view ofthe two sashes, opposite to the side or edge shown in iig. 4.

Figure G is a longitudinal section of the whole window, taken in the line y y, iig. 1.

Figure 7, a detached plan or top view of one of the sashes.

ASimilar letters of reference indicate like parts.

'.lhis invention has for its object the iitting of the sashes within the frame oi' the window in such a manner that the sashes may bc removed from the window-frame and iitted therein with the greatest facility, and without removing or detaehing stops, parting beads, and other parts pertaining to a window-i`ran1e, as is now necessarily required.

A represents the window-frame, which may he constructed in the usual manner, and provided with cords, D, having weights attached, which work within the frame in the ordinary way. The cords B, instead of being attached to the sashes directly, as hitherto, are attached to bars C C', which slide between the stops t and parting-.beads I) of the windowframe. The bars C at one side of the frame are equal in length to one-half of the sash D, (see iig. 2,) while the hars C', at the opposite side of the frame A, are equal in length to the entire height of the sash, (see tig. 4.) The bars C` C are of such a thickness that their outer surfaces will be about iiuslr' with the outer surfaces of the stops and parting beads, and the outer Surfaces of the bars C C' are slightly bevolled, as shown at e, in iig. 6, in order to facilitate the removal of the sashcsafrom between the bars C C', as well as their adjustment between the sashes, the edges or sides ofthe sashes being bcvelled in a similar manner. The sashes D D at one side have hooks, d, projecting from them, which it into holes e, in metal plates f, attached to the short bars C, (see figs. 2 and 3,) andthe opposite sides of the sashes have two hooks, g g, projecting from them, to it into openings It, in metal plates 2', 4attached to the long bars C. The hooks g have. a reverse position to the hooks d, as shown in iig. 7, and slide bolts or catches j are attached to the sashcs D D at the same side where the hooks g are attached, and iit 'in holes lc, in the same plates z' as the openings t.

From the above description it will he seen that in order to remove a. sash from the windowframe, all that is required is simply to shove back the catches jj out from the holes c in the plates t'. In order, however, to admit oi' the lower sash being thus drawn ont, it is necessary that it be raised above the sill piecel of the window-frame, and it is also necessary that the bars G C be held in position, so that they will not be drawn up by thc weights as soon as the sushes arc removed, a contingency which would occur on account ofthe lightness of the bars. ln order to obviate this diiiiculty, the hars C of the lower sash have short bars, E, attached to them by hinges, to catch into notched plates F, secured in the windowfraine, the bar being turned and fitted in the upper notch of the plates F when the sash is to he removed, and said har iitteclin the lower notch to serve as a fastening or bolt when the sash is down, as shown in iig. When the lower sash is to be raised, or when a lower bolt or fastening is not required, the bars E are turned, and iitted in grooves in the Stiles of the sash, as shown in fig. l. The hars C C of thc upper sash D are provided with ,similar hinged bars E', which, when necessary, are fitted in notched plates F in the parting beads b.

'lhus it will be seen that by this simple arrangement the sashcs may be very readily removed from a window and placed therein, a rcsult'not hitherto obtained, and which causes the cleaning, or washing, painting, and

glazing, of sashcs to be attended with considerable diiiiculty, especially those which are conntcrpoiscd or hung with weights. i

Having thus described my invention, I claim es new, and desire to secure by Letters ,Potentl 1. The short bers E, hinged to the hars E of the lower sash, adopted to catch into notched plntes F, secured 'inthe Windowframe, whereby the hers C C are held in position, so that they will not be drown up by the Weight when the sash D is removed, substantially as described, for the purpose specified.

2. The sash D, when provided upon one side with the hooks d, tting into notches of platefupon the short bars C, and upon the opposite side with reversed hooks g, fitting into the notched plates z' upon the'leng bars C', as herein set forth, for the purpose specified. l
